Abstract (en)
Disclosed is a control method of signal source switching, including the following operations: detecting a signal of a signal source when a signal source switching instruction is received; locking the detected signal of the signal source, when the signal of the signal source is detected; judging whether the signal source of the locked signal is the signal source corresponding to the signal source switching instruction currently received; setting image and sound corresponding to the signal source and playing the signal of the signal source, if the signal source of the locked signal is the signal source corresponding to the currently received signal source switching instruction. Further disclosed is a control device of signal source switching. The control method of the present invention can effectively prevent the inconsistency between the signal source of a locked signal and the current signal source during rapid signal source switching.
